Abstract
Description
- This application claims priority to Swiss Patent Application No. CH-01007/11 filed Jun. 16, 2011 the contents of which are incorporated herein by reference.
- The invention relates to a quick-connect coupling for connecting an exchangeable head to a pressing device.
- Pressing devices are used for various purposes, such as, for example, pressing cable shoes onto electrical cables, but also for cutting cables or punching holes into sheet metal constructions. In order to perform these different applications on one machine, an exchangeable head system is required. To simplify matters, the different mountable heads are referred to in the following as exchangeable heads. Using the same pressing device with different exchangeable heads, it is quick and easy to change over to different applications where necessary.
- However, a particular problem affecting pressing devices with exchangeable heads is the longitudinal forces being transmitted, in other words, the compressive forces produced by the pressing devices, because the coupling mechanism by which the exchangeable head is attached to the pressing device naturally has to withstand these forces and the corresponding safety requirements are relatively high. It is advantageous, therefore, to find a coupling mechanism that can be handled quickly and easily and yet offers operational safety, even with high and very high longitudinal forces.
- Quick-connect coupling mechanisms are known per se. A quick-connect coupling mechanism used particularly frequently for torque transmission, especially in the field of hand machine tools, employs a solution with movable locking bodies, usually balls, which engage with corresponding grooves in the exchangeable tool in the connected state. An example of this is known from DE-2 551 125, whereby percussion drills are held in a tool holder on a machine tool in an easily exchangeable manner. Although longitudinal forces are naturally also active here, these are compressive forces (seen in relation to the machine tool/tool connection), so that there is no risk of the quick-connect coupling being released under load by the longitudinal forces and thereby representing a safety risk.
- However, solutions are also known in which the same functional principle is also used with quick-connect couplings, where longitudinal forces are active, which represent traction forces in relation to the parts being connected. An example of this sort of connection is disclosed in DE-1 108 528. This specification shows a valve coupling for hose lines and pipelines. In this case, a coupling sleeve exhibits radial wall bores in which radially movable balls are disposed, which may project into a peripheral groove of a coupling plug. A spring-mounted locking sleeve prevents the balls from slipping out of the peripheral groove. Because this is an application in which pressurised fluids are conducted through connectable lines, although there is a certain safety risk, because evidently no applications involving very high fluid pressures are envisaged, additional measures do not seem necessary.
- The situation is different, however, when the same functional principle is to be used in a quick-connect coupling to connect an exchangeable head to a powerful pressing device. Because relatively high pressures are used in this case (for example>50 kN), special additional measures are needed in order to guarantee safety and reliability.
- It is an object of the present disclosure, therefore, to indicate a quick-connect coupling with loading capacity to connect an exchangeable head to a pressing device, wherein the quick-connect coupling is based on the known construction principle with movable locking bodies in the form of balls, which engage in corresponding grooves in an exchangeable head in the coupled state. This quick-connect coupling should endure high longitudinal traction forces on a sustained basis and, if possible, without wear and guarantee a high degree of safety.
- A further object involves the quick-connect coupling specified being designed in such a way that it is impossible for the pressing device and the interchangeable head to be wrongly assembled.
- The present disclosure involves in principle the use in a generic quick-connect coupling of a further peripheral groove on the exchangeable head, on the one hand, and a greater number of locking bodies (balls) and, on the other hand, a form being provided on the other side on a shaft section of the exchangeable head, which is disposed closer to the pressing device and makes locking impossible if the exchangeable head is used in the wrong position.
- In accordance with the disclosure, a generic quick-connect coupling between a first and a second component should be taken to mean the following in this case: In a ball-holding part on a first component (in this case the pressing device), a number of balls K1 with a diameter D1 is radially movably disposed. On a second component (in this case the exchangeable head) a peripheral groove with a groove depth N1 to partially hold the balls K1 is present on a shaft part in an area with a shaft radius R1 with the first and second components in a connected state. In this case, a locking ring is movably attached to the ball-holding part in an axial direction and in a spring-mounted manner, the balls K1 being held radially fixed in the peripheral groove by said locking ring when the first and second component are in the connected state.
- More particularly, in accordance with the disclosure, it is provided that:
- on the shaft section of the exchangeable head there is a further peripheral groove, which is disposed closer to the pressing device in an axial direction, namely at a distance d from the peripheral groove,
- the further peripheral groove is designed to hold further balls K, wherein the further balls K are likewise disposed in a radially movable manner in the ball-holding part and wherein the further balls K are likewise spaced at a distance d, and
- the shaft section is disposed in an area that is closer to the pressing device in an axial direction and is likewise spaced at a distance d from the further peripheral groove, exhibits a form A that prevents the further balls K from moving radially when contact is made with the further balls K and thereby prevents the locking ring from moving.
- By using a further peripheral groove and with the associated use of a larger number of locking bodies (balls), it is possible to achieve the transmission of smaller forces per locking body (ball), or else the transmission of greater forces using the same measure. The form A on the shaft section of the exchangeable head mean that if the exchangeable head is not completely inserted into the ball-holding part on the pressing device, a fixed connection cannot be made (in other words, a connection in which power is only transmitted across a single peripheral groove and the locking bodies engaging with it). Non-lockability in the event of incorrect assembly is notably important, because this is exactly what must be completely and reliably prevented, due to the associated risks (breakage of the quick-connect coupling when there is a build-up of pressure). The present disclosure has the added advantage that an embodiment functions purely mechanically and does not require electronic monitoring.
- It has also emerged that with two peripheral grooves and a total of at least 12 balls—and of course using tool steels that are sufficiently hard and tough to avoid lasting deformation—the specified longitudinal forces in the region of 60 kN can be reliably transmitted.
- Also advantageous is an angularly offset arrangement of the balls K in the peripheral groove compared with the further balls K in the further peripheral groove. The forces can thereby be more effectively distributed over the entire cross-section.
- A further advantage is also that an arrangement of the embodiment facilitates the unlimited twistability of the exchangeable head in relation to the pressing device.
- A further measure that ensures that the quick-connect coupling is able to withstand high longitudinal traction forces on a sustained basis and with as little wear as possible, involves the peripheral grooves each being provided with a base surface and side faces, namely in such a way that the balls K and the further balls K have a point contact with the base surface and the side faces in the connected state and that the point contact with the side face is made roughly in the region of the half groove depth N. This means that the locating point of the balls is moved from the entry edge of the peripheral grooves sensitive to deformation towards the entry centre of the peripheral grooves, which significantly increases wear resistance.
- A more complete understanding of the present invention, and the attendant advantages and features thereof, will be more readily understood by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:
-
FIG. 1 shows a theoretical sectional drawing of an exchangeable head not yet inserted in the quick-connect coupling with the locking ring in an unlocked position; -

FIG. 3 shows a theoretical sectional drawing of an exchangeable head completely inserted in the quick-connect coupling with the locking ring in a locked position; and -
FIG. 4 shows a sectional detail drawing of the quick-connect coupling for the theoretical shaping of the peripheral grooves. - As required, detailed embodiments are disclosed herein; however, it is to be understood that the disclosed embodiments are merely examples and that the systems and methods described below can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present subject matter in virtually any appropriately detailed structure and function. Further, the terms and phrases used herein are not intended to be limiting, but rather, to provide an understandable description of the concepts.

The term another, as used herein, is defined as at least a second or more. The terms “including” and “having,” as used herein, are defined as comprising (i.e., open language).

-
FIG. 1 shows a theoretical sectional drawing of anexchangeable head 1 not yet inserted in the quick-connect coupling with alocking ring 2 in an unlocked position. In this case, thelocking ring 2 and a ball-holdingpart 3 are parts of the quick-connect coupling, which are connected to apressing device 4. In the ball-holdingpart 3, balls K1 with a diameter D1 and further balls K2, likewise with the diameter D1, are disposed inball guides part 3. Furthermore, the ball-holdingpart 3 and theexchangeable head 1 are adjusted to one another, such that there is a sliding fit. Special shaping (seeFIG. 4 ) of the ball guides 5, 6 on the inside of the ball-holdingpart 3 also prevents the balls K1, K2 from falling out when theexchangeable head 1 is not inserted or not inserted fully. - The
locking ring 2 is mounted on the ball-holdingpart 3 in an axially movable manner. Thelocking ring 2 has locatinggrooves grooves locking ring 2 is in the unlocked position—as shown here—and thereby avoid obstructing the insertion of theexchangeable head 1. Not shown in this figure is a spring element 9 that is mounted between the ball-holdingpart 3 and thelocking ring 2 and permanently tries to press the lockingring 2 in an axial direction into the locking position (seeFIG. 3 ). In order to achieve the unlocked position of thelocking ring 2, as shown, thelocking ring 2 must therefore be moved into this position manually by means of a gripping bar (not shown). - Since the quick-connect coupling described creates a mechanically secure, but detachable connection between the
pressing device 4 and theexchangeable head 1 and thepressing device 4 transmits compressive forces onto theexchangeable head 1, there is a plunger within thepressing device 4, via which pressure is transmitted onto an axially spring-mounted connecting rod within theexchangeable head 1 during operation by means of a contact surface on the plunger tip. To simplify the theoretical illustration and because they are not basically needed in order to understand the quick-connect coupling, these elements are not shown here. During operation, however, the quick-connect coupling is exposed to high axial forces with this sort of use, which act as traction forces and pull thepressing device 4 and theexchangeable head 1 apart. - The
exchangeable head 1 has ashaft part 13 with a shaft radius R1. The shaft radius R1 of theexchangeable head 1 corresponds to the inside radii of the ball-holdingpart 3, naturally with corresponding tolerances for an easy-to-use sliding fit, because various exchangeable heads must be attachable to the pressing device. - The
exchangeable head 1 has aperipheral groove 14 with a groove depth N in the area of theshaft part 13 with the shaft radius R1. Theperipheral groove 14 serves the partial holding of balls K1 with thepressing device 4 and theexchangeable head 1 in the connected state. Theshaft part 13 has a furtherperipheral groove 15, likewise with the groove depth N and likewise in the area of theshaft part 13 with the shaft radius R1. Theperipheral groove 15 serves to partially hold the balls K2 with thepressing device 4 and theexchangeable head 1 in the coupled state. The furtherperipheral groove 15 is disposed in the axial direction closer to thepressing device 4. In addition, theperipheral groove 14 and the furtherperipheral groove 15 naturally have the same axial spacing as the balls K1 and K2 in the ball-holding part, namely at a distance d. - Based on the sizes introduced, it is easy to establish that with the proposed structural form with balls K1, K2 of the same size (i.e. the same diameter D1) and the same groove depth N for both
grooves FIG. 3 . - It is also true that with a structure of the type shown with the
shaft part 13 in an area disposed closer to thepressing device 4 in an axial direction and at a distance d from the furtherperipheral groove 15, there is a form A, which prevents the further balls K2 from moving radially when contact is made with the further balls K2 and therefore prevents thelocking ring 2 from moving. In this case, the form A is executed in its simplest form as an extension of the shaft part end with a constant radius R1 at least at a distance d from the secondperipheral groove 15. Other detail embodiments with the same effect are naturally possible. This form A means that no connection can be made between theexchangeable head 1 and thepressing device 4, in which the transmission of force only takes place via a single peripheral groove and the locking bodies (balls) engaging with it. This means that even in the case illustrated inFIG. 2 , where theexchangeable head 1 is only inserted far enough for the furtherperipheral groove 15 to be located in the area of the balls K1—a position in which thelocking ring 2 cannot be pushed into the locking position, due to the form A and the resulting blocking effect of the further balls K2—no fixed connection can be made between theexchangeable head 1 and the pressing device, because the balls K1 can then still move way and are not fixable in the furtherperipheral groove 15. -
FIG. 3 shows a theoretical sectional drawing of anexchangeable head 1 completely inserted in the quick-connect coupling with thelocking ring 2 in a locked position. It is made clear here that both the balls K1 and the further balls K2 are fixed in their radial position by stoppingsurfaces exchangeable head 1 and the advancing of the locking ring 2 (which is supported by the spring element 9), such that they have no more freedom of movement and theexchangeable head 1 is therefore locked in the quick-connect coupling. The balls K1, K2 now engage as a fixed locking body both with theshaft part 13 and also with the ball-holdingpart 3 and therefore prevent reciprocal movement. -
FIG. 4 shows a detail of a sectional drawing of the quick-connect coupling for the theoretical shaping of theperipheral grooves FIG. 3 and is the same in principle for bothperipheral grooves peripheral grooves peripheral grooves peripheral grooves - However, in order to keep the permanent deformation by balls K1, K2 as small as possible with the great forces anticipated F, tests have revealed that the hardness of the steel used for the
shaft part 13 of theexchangeable head 4, for the ball-holdingpart 3 and for thelocking ring 2 must be at least 60 HRC. Apart from the high hardness level, the steels used must also exhibit adequate toughness. - It will be appreciated by persons skilled in the art that the present invention is not limited to what has been particularly shown and described herein above. In addition, unless mention was made above to the contrary, it should be noted that all of the accompanying drawings are not to scale.
